This applet can be used to model arithmetic of integers with two color counters. The yellow "chips" represent +1, and the red "chips" represent -1.

## Play time! What do you notice?

## Let's show the addition problem: 2 + 4

## Let's show the addition problem: -4 + (-3)

## Let's show the addition problem: -6 + (-2)

## Let's show the addition problem: 5 + (-3)

## Use the counters above to help you solve the addition problems below. Copy the problem and write the sum.

1. 7 + (-7)
2. -5 + 5
3. 10 + (-4)
4. -5 + 9
5. -7 + 2
6. 3 + (-8)
